Summary
This study introduces a coherent on receive marine radar system. It enables precise measurement of oceanographic and meteorological data, enhancing marine monitoring capabilities.
Area of Science:
- Oceanography and Meteorology
- Radar Engineering
Background:
- Marine radars are vital for monitoring ocean surface wind, waves, currents, bathymetry, and shorelines.
- Existing incoherent radars have limitations in precise parameter retrieval.
Purpose of the Study:
- To introduce a novel coherent on receive marine radar system.
- To demonstrate its capability in retrieving oceanographic and meteorological parameters.
Main Methods:
- Utilizing an off-the-shelf pulsed X-band radar.
- Implementing a coherent on receive principle using a circulator leak for phase reference.
- Computing Doppler shift frequencies via pulse-pairs or Fast Fourier Transform (FFT).
Main Results:
- Successfully retrieved radial speed maps of ocean surface backscatter.
- Generated backscatter intensity and Doppler speed maps for horizontal and vertical polarization.
- Demonstrated the system's potential for meteorological and oceanographic applications.
Conclusions:
- The developed coherent on receive marine radar effectively enhances marine monitoring.
- This technology offers improved accuracy for oceanographic and meteorological data acquisition.

01:07Propagation of Waves
2.5K
When a wave propagates from one medium to another, part of it may get reflected in the first medium, and part of it may get transmitted to the second medium. In such a case, the interface of the two mediums can be considered as a boundary that is neither fixed nor free.
Consider a scenario where a wave propagates from a string of low linear mass density to a string of high linear mass density. In such a case, the reflected wave is out of phase with respect to the incident wave, however the...

01:26Raman Spectroscopy Instrumentation: Overview
585
A conventional Raman spectrophotometer includes a laser source, a sample holding system, a wavelength selector, and a detector.
The monochromatic laser source, typically using visible or near-infrared radiation, generates a highly focused beam of light. This light interacts with the molecules of the sample, scattering some of the light. Liquid and gaseous samples are usually tested in ordinary glass capillaries, while solids can be analyzed as powders packed in capillaries or as potassium...

German physicist Wilhelm Röntgen (1845–1923) was experimenting with electrical current when he discovered that a mysterious and invisible "ray" would pass through his flesh but leave an outline of his bones on a screen coated with a metal compound. In 1895, Röntgen made the first durable record of the internal parts of a living human: an "X-ray" image (as it came to be called) of his wife’s hand. Scientists worldwide quickly began their own experiments with...

GPS surveying methods vary in application, accuracy, and data collection techniques, catering to diverse surveying and mapping needs. Static GPS, kinematic GPS, and real-time kinematic (RTK) surveying are widely used. Each technique offers distinct advantages.Static GPS involves placing one receiver at a known reference point and another at the target point. It collects exact positional data by observing multiple satellite ranges over an extended period, achieving centimeter-level accuracy for...

James Clerk Maxwell formulated a single theory combining all the electric and magnetic effects scientists knew during that time, calling the phenomena his theory predicted “Electromagnetic waves”. He brought together all the work that had been done by brilliant physicists such as Oersted, Coulomb, Gauss, and Faraday and added his own insights to develop the overarching theory of electromagnetism. Maxwell’s equations, combined with the Lorentz force law, encompass all the laws...

01:15Standing Electromagnetic Waves
1.8K
Electromagnetic waves can be reflected; the surface of a conductor or a dielectric can act as a reflector. As electric and magnetic fields obey the superposition principle, so do electromagnetic waves. The superposition of an incident wave and a reflected electromagnetic wave produces a standing wave analogous to the standing waves created on a stretched string.
